【 摘 要 】

The Bragg-like curve for compounds is introduced for directional detection of galactic dark matter. The slow ion collisions are discussed in relation to direct dark matter searches. The Coulomb effect and the threshold effect in stopping power theory are examined. Ionization via molecular orbit (MO) is suggested for an additional contribution to the electronic stopping power at very slow energy.
