Short answer. Half and half. Under Article 1001, when a person dies leaving a spouse and brothers and sisters (or their children) but no descendants and no parents, the surviving spouse takes one-half of the inheritance and the brothers and sisters, or their children, share the other half.
What the law says
the latter shall be entitled to one-half of the inheritance and the brothers and sisters or their children to the other half.

The situation the rule addresses
Article 1001 governs a specific intestate scenario: the deceased left no descendants and no surviving parents or other ascendants, but is survived by a spouse together with brothers and sisters, or the children of deceased brothers and sisters. With no children or parents in the picture, the estate is shared between two groups, the widow or widower on one side and the collateral relatives, the siblings and their children, on the other. The article fixes how much each side takes.
A fifty-fifty division
The split is equal between the two sides. The article provides that where brothers and sisters or their children survive with the widow or widower, the latter shall be entitled to one-half of the inheritance and the brothers and sisters or their children to the other half. So the surviving spouse receives one-half of the estate outright, and the deceased's siblings collectively receive the remaining half. The spouse's share does not shrink with the number of siblings; whether there is one sibling or several, the spouse still takes half and the siblings divide the other half among themselves.
How the siblings' half is shared
Within their one-half, the brothers and sisters divide according to the ordinary rules. Full-blood and half-blood siblings may share in different proportions, and the children of a sibling who predeceased the decedent take that sibling's portion by representation, stepping into their parent's place. So a deceased brother's children do not inherit in their own right alongside living siblings; they collectively take the share their parent would have received. The spouse's half is unaffected by how the siblings' half is subdivided among themselves.
Practical effect for a surviving spouse
For a widow or widower in this situation, the practical result is reassuring but not total: the estate is not inherited entirely by the surviving spouse when the deceased's siblings survive and there are no children or parents. The spouse takes a full half, and the siblings, or their children by representation, take the other half. Settling the estate therefore means identifying the surviving siblings and any children of predeceased siblings, dividing their collective half among them, and allotting the remaining half to the surviving spouse.
