modification of the Nuclear Energy Level width
EPL, 2005Co-Authors: Ilt CheonAbstract:A possible method is proposed to modulate the Nuclear γ-decay constant which is related to the lifetime. When the radioactive 133Cs nucleus embedded in a compound is placed between two silver plates and separated by 0.02 cm from each plate, the width of 81 keV excited Level turns out to be 6.90 × 10−8 eV at 4.2 K, which is about 4% narrower than the natural line width, 7.27 × 10−8 eV. This implies 5.4% increase of the lifetime.

effects on the gamma rays scattered backward by the gold cylinder on the Nuclear Energy Level
Journal of The Korean Magnetics Society, 2007Co-Authors: Moon Taeg Jeong, N G Chol, M K CheounAbstract:When the gamma-ray source, , embedded in a solid is placed at the center of a gold cylinder, the width of 81 keV Level is shown to become narrower. This result implies a prolongation of the lifetime of that Energy Level. With a 0.5-mm-thick, 5-cm-long, 2-mm-diameter platinum cylinder, we obtain a width narrower by 6.1 % at 4.2 K.

effects of the gamma rays scattered backward by metals on the Nuclear Energy Level width
arXiv: Nuclear Theory, 2006Co-Authors: Iltong Cheon, Moon Taeg JeongAbstract:By placing a ${}^{133}Cs$ $\gamma$-ray source embedded in a solid at the center of a platinum (gold) cylinder, we try to change the width of the 81-keV Level. Our results show a narrowed Energy Level and, equivalently, a prolonged lifetime. With a 0.5-mm-thick, 5-cm-long, 2-mm-diameter platinum cylinder, we obtain a width narrower by $6.1 % $ at $4.2 \: K$.
