“…Results based on our calculation shown that the muon reactivation increases when the average number of X-rays per sticking reduces with increasing density. Our calculated results are in good agreement with available experimental data (Ishida, Nagamine et al, 1999;Petitjean et al, 1993;Breunlich et al, 1987;Bossy et al, 1987;Jones, Taylor & Andeson, 1993;Nagamine et al, 1993;Ishida et al, 2001;Petitjean, 2001) 0.57 0.07 --- (Markushin, 1988) 0.57 0.36 (Refelski et al,1989) 0.664 0.248 (Takahashi, 1987) 0.59 --- (Cohen, Hale, Hu, 1996) Experimets 0.39 0.10 ---PSI (Bossy et al, 1987) 0.45 0.05 ---PSI (Breunlich et al, 1987) 0.48 0.02 0.04 ---PSI (Petitjean et al, 1993) 0.43 0.05 0.06 ---LAMPF (Jones, Taylor & Andeson, 1993) 0.51 0.004 ---KEK (Nagamine et al, 1993) 0.434 0.030 ---RIKEN-RAL, Liquid (Ishida, Nagamine et al, 1999) 0.421 0.030 RIKEN-RAL, Solid (Ishida, Nagamine et al, 1999) 0.532 0.030 ---RIKEN (Ishida et al, 2001) 1.45 Density LHD 0.551 0.395 Experiment 0.505 0.029 ---PSI (Petitjean, 2001) Table 3.
