Role reversal in #proton capture

Role reversal in #proton capture | Nuclear Physics | Scoop.it
A novel technique for measuring nuclear reaction cross sections may yield long-sought parameters for short-lived isotopes.
Theo J. Mertzimekis's insight:

The idea of inverse kinematics has been around for some time. The implementation is quite hard. We have tried similar things with a He cryogenic target, without large success. I am very glad Rene Reifarth and colleagues managed to do it with protons.

Induced magnetic moment in stainless steel components of orthodontic appliances in 1.5 T MRI scanners

Induced magnetic moment in stainless steel components of orthodontic appliances in 1.5 T MRI scanners | Nuclear Physics | Scoop.it
Purpose:
Most orthodontic appliances are made of stainless steel materials and induce severe magnetic susceptibility artifacts in brain
MRI. In an effort for correcting these artifacts, it is important to know the value of induced magnetic moments in all parts of orthodontic appliances. In this study, the induced magnetic moment of stainless steel orthodontic brackets, molar bands, and arch-wires from several vendors is measured.
Methods:
Individual stainless steel brackets, molar bands, and short segments of arch-wire were positioned in the center of spherical flask filled with water through a thin plastic rod. The induced magnetic moment at 1.5 T was determined by fitting the B
0 map to the z-component of the magnetic dipole field using a computer routine.
Results:
The induced magnetic moment at 1.5 T was dominated by the longitudinal component mz
, with a small contribution from the transverse components. The mz
was insensitive to the orientation of the metal parts. The orthodontic brackets collectively dominated the magnetic dipole moment in orthodontic appliances. In brackets from six vendors, the total induced mz
from 20 brackets for nonmolar teeth ranged from 0.108 to 0.158 (median 0.122) A ⋅ m2. The mz
in eight molar bands with bracket attachment from two vendors ranged from 0.0004 to 0.0166 (median 0.0035) A ⋅ m2. Several full length arch wires had induced magnetic moment in the range of 0.006–0.025 (median 0.015) A ⋅ m2.
Conclusions:
Orthodontic brackets collectively contributed most to the total magnetic moment. Different types of brackets, molar bands, and arch wires all exhibit substantial variability in the induced magnetic moment.

Steady-State Free Precession in Nuclear Magnetic Resonance

Steady-State Free Precession in Nuclear Magnetic Resonance | Nuclear Physics | Scoop.it
A steady-state free precession technique for observing nuclear magnetic resonance is described. A mathematical analysis is presented for certain special conditions, and initial experiments verifying the results of this analysis are reported. This technique provides two opportunities for improving the signal-to-noise ratio. First, it provides a mechanism, similar to that of the "spin echo," for eliminating the effect of the inhomogeneity of the magnetic field on signal strength. This permits the

Nuclear Magnetic Resonance Line Shape for a Triangular Configuration of Nuclei

Nuclear Magnetic Resonance Line Shape for a Triangular Configuration of Nuclei | Nuclear Physics | Scoop.it
The nuclear resonance line shape observed in solids can often be accounted for quantitatively and (in the absence of quadrupole effects) may provide information concerning the orientation and internuclear distances of dipolar nuclei. As an example of this method, the line shapes for a rigid and rotating triangular configuration of such nuclei are calculated and compared with recent experiments.
Theo J. Mertzimekis's insight:

A great paper from the 1950's

“Rutherford, this is transmutation!”
“For Mike’s sake, Soddy, don’t call it transmutation. They’ll have our heads off as alchemists.”
