  In this work we prove that for any dimension $d\geq 1$ and any $\gamma \in
(0,1)$ super-Brownian motion corresponding to the log-Laplace equation
\begin{equation*} \begin{split} \frac{\partial v(t,x)}{\partial t } & =
\frac{1}{2}\bigtriangleup v(t,x) + v^\gamma (t,x) ,\: (t,x) \in
\mathbb{R}_+\times \mathbb{R}^d,\\ v(0,x)&= f(x) \end{split} \end{equation*} is
absolutely continuous with respect to the Lebesgue measure at any fixed time
$t>0$. Our proof is based on properties of solutions of the \LL\ equation.
  We also prove that when initial datum $v(0,\cdot)$ is a finite, non-zero
measure, then the \LL\ equation has a unique, continuous solution. Moreover
this solution continuously depends on initial data.
