... • Galactic tide: We assume that the density of solar neighborhood is 0.1 M⊙/pc3, and also that Oort’s constants of galactic rotation A = -B = 13 km/s/kpc, that means we neglect differential rotation of Galaxy, see Levison, H.F., Dones, L., & Duncan, M.J. 2001 [AJ 121, 2253] for further details. • St ...

Developing an Efficient Low-Temperature Nuclear Fusion Reactor
... In the past few years, a very large amount of screening energy was also obtained for Li+D reaction. This is an expansion of nuclear reactions other than D+D reactions. This large energy obtained for Li+D reaction for certain metals raises the important question whether these large values are due to ...

... as as one of the parameters ( as ms ) is varied from -134 MeV to -310 MeV. This parameter depends on the strangeness content of the nucleon ( varying from 0 to 0.2 ). Now, the neutrino scattering experiments[10] indicate that the strangeness content of the nucleon is ∼ 0.06. It therefore appears th ...
