Nuclear coherent population transfer with x-ray laser pulses
Nuclear coherent population transfer x-ray laser pulses
2010/12/27
Coherent population transfer in a nuclear three-level system via stimulated Raman adiabatic passage is studied. To compensate for the lack of $\gamma$-ray laser sources, we envisage accelerated nucle...
Measurements of nuclear $\gamma$-ray line emission in interactions of protons and $\alpha$ particles with N, O, Ne and Si
Measurements of nuclear $\gamma$-ray line emission interactions of protons $\alpha$ particles with N, O, Ne and Si
2011/1/4
$\gamma$-ray production cross sections have been measured in proton irradiations of N, Ne and Si and $\alpha$-particle irradiations of N and Ne. In the same experiment we extracted also line shapes fo...

Particle tracking detectors (Solid-state detectors) Detector alignment and calibration methods
2010/3/15
ALICE (A Large Ion Collider Experiment) is the LHC (Large Hadron Collider) experiment devoted to investigating the strongly interacting matter created in nucleus-nucleus collisions at the LHC energies...
Experiment of Xray Generations Using LaserCompton Scattering at LINAC of SINAP
Nd∶YAG laser γray source polarization
2009/10/29
Laser Compton scattering(LCS) can generate Xrays or γrays with high brightness and easy controlled polarization by applying highpeakpower laser pulses to relativistic electron bunches. One of the ...
In this proceeding, we will first outline the experimental setup and main results of the most recent hypernuclear γray spectroscopy experiment (KEKE566) performed at KEKPS K6 beam line. The main fe...
